Kimball Brace of Election Data Services in Virginia said he projects that Oregon should gain another seat with about 140,000 people to spare. That’s relatively close, but not as close to the margin as it is for some states.

“There are still some potential changes coming that could impact Oregon,” he said. These include population changes caused by a disaster or an economic shock — or big differences in what the Census Bureau turns up when it attempts to count the entire population in 2020.
